When using the vacuum cleaner, instead of sucking the nozzle hard against the seat, you must first blow away the dirt before sucking. The dust that sticks to the car can be sucked up by a vacuum cleaner. In fact, very few, especially vacuum cleaners for households and small vacuum cleaners for cars, their suction power is even lower.

For dust that can't be vacuumed up, use a duster to slap it out of the car. For example, for a seat made of flannel, you can dust off the dust that got into the cushion first, and then use the vacuum cleaner, so the effect is better. It should be noted that when dusting the dust, the force should not be too large, otherwise the dusted object will be easily damaged. In addition, when dusting, there is a lot of dust flying in the car, so the door must be fully open, and the air conditioner must be turned on to the maximum to blow the dust out of the car.

Before using the vacuum cleaner, you can put a layer of stockings on the junction of the front nozzle and the hose, which becomes a very useful filter that can improve the vacuuming efficiency. Maybe you think your seat should be clean, but you can tell by looking at the stockings that there is actually a lot of cotton wool on them.

The benefits of a simple filter made of stockings don't stop there. Due to the structure of the vacuum cleaner itself, the sucked air can be discharged from the inside. There is a simple stocking-type filter and the filter of the vacuum cleaner itself to form a two-stage filter, which can prevent the vacuum cleaner from re-discharging dust in the car at the discharge port. If you still feel unsafe, you can also stick a wet paper towel on the discharge port. In this way, the filter effect will be better, and it can also prevent the emission of odors.
